Abstract
When a periodic pattern is not included in image data, a prediction error encoding unitoutputs the variable-length code of a prediction error quantization valuegenerated by prediction encoding as compressed data. When the periodic pattern is included in the image data, a periodic pattern encoding unitoutputs only information about the periodic pattern as the compressed data, while the output of the prediction error encoding unit is stopped. On the decompression side, while the copy instruction of a pixel value before one cycle from the compressed data is not detected, the decompression operation in a normal prediction encoding system is executed. When the instruction is detected, the pixel value one cycle before, internally stored is copied and outputted.
